Hi all, i'm looking to buy a mid 70s FJ40, right now i'm seeing between 10-15mpg on these. I'm also a novice to this sort of thing, but how could i increase that and still maintain power/offroadability? Thanks!

Port and polish and the bigger valves is a waste of time.FJ40onNOS said:i was getting about 12MPG, i had a Weber 38, header, 3.73 gears and 33in tires.
my motor only lasted me 17,000 miles, so now its rebuild time.
i am planning on running a MAF RV Cam, the Weber, header, try to have the head wet flowwed, ported and polished, and some bigger intake and exhuast valves. i still need to check on prices of it all, so once im all done and back on the road ill post my new MPG

Morse_FJ40 said:Mace, I would have to disagree with you on that statement about port and polishing. The valves might not help, but gasket matching and polishing the head would make a huge difference. The thing would flow much better!!! Less resistance since the air chambers had been polished.
